Michelle Obama in Cincinnati on first day of early voting

First Lady Michelle Obama plans a campaign event in Cincinnati on Oct. 2, the first day of early voting in Ohio; and campaign aides say that is no coincidence.

The First Lady can be expected to try to gin up a large turnout of Democratic voters for the first day of the 35-day period where Ohio voters can vote by absentee ballot or in person at their county boards of elections.

No details on Mrs. Obama's Cincinnati visit have been released yet.

The Obama-Biden campaign is pushing hard to maximize the number of early voters in Ohio, a critical battleground state in the Nov. 6 election.

Meanwhile, her husband will be campaigning in Ohio this week.
